...and have enjoyed wearing. I kept this 1960s Wittnauer Geneve on the interesting Kestenmade bracelet it came on, with a flexible brick pattern on the front half and an expanding scissors section at the back. I like the way it flexes and it feels quite comfortable. The slim edge profile of the watch case lends it a thinner look than the thickness of the "meat" of the watch would imply.

It's a front-loader - here's the cal. D11KAS movement, based on the Record cal. 1958 and also used by Longines as their cal. 503. Longines-Wittnauer were combined in the 1950s and the brands were marketed together in the US.
